Collagen Supplements – Which Work and Why?

Collagen is at the root of pretty much all anti-ageing treatments and collagen supplements have become more and more popular in recent years. Most collagen supplements out there are largely ineffective but don’t worry we’re here to help. In this blog find out what collagen is, why it’s important and which supplements actually work.

Why Your Skin Needs Collagen

Collagen is a protein that is naturally produced in the body. It is a major component of connective tissues including skin, muscles, tendons, and ligaments. It’s also linked to a vast range of anti ageing products.

It plays a vital role in strengthening the skin by helping skin cells adhere to one another. It also benefits skin elasticity and boosts hydration.

Collagen supplements become increasingly more important as we age. With age, our bodies produce less collagen which can lead to dry skin and the formation of wrinkles.

The Benefits of Collagen Supplements

Collagen Supplements stimulate the body to produce collagen which:

  • Has anti-ageing benefits
  • Boosts skin elasticity
  • Hydrates skin
  • Helps eliminate deep wrinkles
  • Boosts production of other proteins that your skin and body need
  • Supports muscle maintenance
  • Supports strong & healthy bones
  • Strengthens hair and nails

Why Collagen Supplements Are Important For Your Skin

Protein-rich foods, like meat, eggs, fish, beans, and dairy all supply the body with a range of amino acids that are needed to make collagen. However, the foods we eat have become increasingly processed over time which has led to the reduction of our intake of vitamins and minerals.

This means we are often finding ourselves not getting the amount we need to meet our needs, which is where supplements come in.

Though our bodies produce collagen naturally, studies suggest that the amount in our skin may decrease by 1% each year. This leads to our skin showing the visible signs of ageing. This is why collagen supplements are necessary, especially as we grow older.

A study of 114 middle-aged women who took 2.5 grams of a branded hydrolyzed collagen daily for 8 weeks found that the volume of wrinkles was reduced by 20%.¹

There was a second study conducted on 72 women aged 35 years or older. The women took 2.5 grams of hydrolyzed collagen daily for 12 weeks and found that wrinkle depth was reduced by 27%. Skin hydration was also found to have increased by 28%.²


Collagen Creams Don’t Work!

Collagen creams are marketed as a solution against the visible signs of ageing, but they are highly ineffective and their effectiveness has been challenged by leading dermatologists.

Collagen molecules are large which makes it difficult for them to penetrate the skin’s surface. When applied topically on the surface of the skin, they’re unable to penetrate deep into the dermis layers.

So while creams may make your skin feel nicer due to the hydrating nature of them, in terms of boosting collagen levels, they’re redundant.

We need to stimulate the body to produce collagen by supplying it with the necessary peptides. Rather than stimulating production, creams simply spread the molecules across the surface of the skin which has no benefits.


Why You Should Avoid Tablet Collagen Supplements

Most supplements that come in tablet forms aren’t very effective. For a dietary supplement to be absorbed properly it needs to be both water soluble and oil soluble. This is near impossible to achieve with tablet forms.

If a nutrient isn’t able to be properly absorbed by the body, bioavailability is massively reduced. Most tablet supplements aren’t cost effective as the levels of the nutrient that are actually being absorbed into the body is dramatically decreased.

Once tablet jars are opened the packaging is no longer airtight. This allows the dietary supplement to come into contact with the air which then causes it to oxidise.

Liposomal Collagen Supplements Are The Future

Liposomal drug delivery is a revolutionary new way of transporting important substances into the body effectively. This includes the amino acids which are necessary for the body to produce collagen. This unique drug delivery system is transforming the way that we take our daily supplements.

In liposomal drug delivery systems, the amino acids are wrapped in liposomes, which are tiny bubbles of phospholipids. The liposomes shield, protect and deliver the supplements through the digestive system and into the bloodstream.

The amino acids are then dispersed and pass through our cell walls to be absorbed. The liposomes are made up of the same lipids that are found in our cells which is what allows them to pass through the walls. This ultimately leads to better absorption, and increased bioavailability.

Like tablets, liposomal supplements are taken orally, They either make absorption directly in the mouth easier or prevent stomach acids prematurely breaking down the nutrient.

For a dietary supplement to be absorbed properly it needs to be both water soluble and oil soluble. In Liposomal delivery, the supplements come in liquid form and have already been suspended in water.

The nutritional industry’s use of liposomes is expected to grow rapidly over the next 10 years.


The Benefits of Liposomal Collagen Supplements

Liposomal collagen supplements offer an effective alternative to anti-ageing surgery. It offers wrinkle reduction, as well as skin hydration and tightening, without the use of cosmetic surgery, botulinum toxin injections or dermal filler injections.

Collagen supplements also offer an effective strategy to target the effects of ageing from under the skin. Rather than just masking the visible effects of ageing like surgery and injections, supplements work from within to reverse the physical signs of ageing.

They also offer a needle-free alternative for those who can’t stand the thought of a needle being anywhere near their face. Additionally, not everyone is capable of swallowing tablets so liposomal collagen supplements offer a substitute.

Due to increased bioavailability, liposomal supplements are more cost effective than tablet supplements as you need a lower dosage to achieve good effects.

The Best Collagen Supplements On The Market

YourZooki is the first marine collagen supplement in the UK to use liposomes to increase absorption and effectiveness. Each sachet contains 5000mg of Liposomal Hydrolysed Marine Collagen with 30mg of Vitamin C. Vitamin C intake is also essential for the formation of collagen in the body.

YourZooki opted to use ‘marine collagen’ rather than collagen sourced from cows and pigs.

Marine collagen primarily contains type 1 collagen, the most prevalent type of collagen within the body, with a little type 3 collagen and a whole range of different amino acids. Marine collagen is also easier for the body to absorb compared to other sources such as bovine or porcine.

By wrapping collagen peptides in phospholipids, they are able to pass through the digestive system without oxidising or being damaged by the harsh internal environment. This allows for full absorption of the supplements.

The phospholipids that make up the liposomes also come from non-GMO sunflower oil high in phosphatidylcholine. All ingredients are also 100% natural.

The Collagen Zooki is flavoured with natural lime extracts too. This means it can be taken in the morning on its own sachet, or mixed in with water, smoothies, yoghurt, porridge, granola and more.
